Wiring towbar electrics for nissan navara d40

The best, and in fact the only recommended solution is to use a plug-in dedicated wiring kit for this car, it plugs into a grey connector on the chassis on the rear of the left hand side. this is the connector that the cars rear light loom is plugged into and the towbar loom piggybacks onto this using the same watertight sealed connectors. There is a trailer indicator warning light already built into the dash display so no need for any other monitoring of the trailer functions. This wiring kit should cost you around £40-£50 and will only take around 10mins to fit. The other alternative is to solder the towbar wires to the cars loom, but this is time consuming and may invalidate the vehicles warranty.
